Pathophysiology of Myocardial Infarction (MI)
Myocardial infarction (MI), also known as a heart attack, occurs when the blood supply to a portion of the heart muscle is blocked, causing damage or death to the heart muscle. The most common cause of MI is atherosclerotic plaque rupture, which occurs when a buildup of plaque in the coronary arteries ruptures and blocks the blood flow to the heart muscle. Other causes of MI include coronary artery spasm, blood clots, and embolism.
